THREA=CUTTHNG TEMPLE FOR LQOEVES.

SPECIFICATION forming part of Letters Patent No. 604,632, dated May 24:,1898. Application filed December 6, 1897. Serial No. 660,866. (Nomodel.)

To (LZZ whom it may concern:

Be it known that 1, JAMES H. NORTHROP, of Hopedale, county oflVorcester, and State of Massachusetts, have invented an Improvement inThread-Cutting Temples for Looms, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention relates to that class of loomtemples more particularlyadapted for socalled automatic looms, wherein the filling is supplied tothe shuttle in the shuttle-box while the loom is running, a freshfi1ling-carrier being inserted into the shuttle while the more or lessexhausted filling-carrier is ejected therefrom upon breakage or failureof the filling. Each insertion of a fresh filling-carrier leaves outsideof the selvage a filling end, and a thread-cutting temple has beendevised to sever this filling end before the temple is moved toward thebreast-beam as. the lay beats in the filling, as in United States PatentNo. 585,465, dated June 29, 1897. It is customary to attach a strip ofleather to the lay to cushion or break the force of the blow upon thetemple, and in order to permit the proper adjustment of the temple fordifferent widths of goods the leather strip must be of considerablelength. In my present invention I mount the cushion on the temple,thereby greatly reducing the amount of cushioning material required andlessening the expense, and, furthermore, the operation of the device isimproved.

Figure l is a top or plan view of a threadcutting temple with myinvention applied thereto. Fig. 2 is a side elevation thereof, and Fig.3 is a front end elevation thereof.

The stand A, adapted to be secured to the breast-beam of the loom, theslide-bar B, having the pod B, the cap B the heel B attached to the pod,and the toothed roller B are and may be all as usual.

The blade co in the slotted pod, the slotted ear I) on the bar B toreceive the body 0 of the thread-cutter 0, (shown as slotted to leavetwo hooked arms 0 o and straddling the blade 6a,) and the spring cl, oneend of which engages the heel c of the cutter to retain the cutter inits normal forward position, with its cutting end out of the plane ofthe filling end, may be and are substantially as shown in the UnitedStates Patent No. 585,465, to which reference may be had.

As shown in Fig. 3, the heel B is at one side of the heel o of thecutter, and the latter is in advance of the former, to be engaged firstby the lay as it heats up to thereby first rock the cutter, placing thehooked end thereof behind the filling end, the further forward movementof the lay causing the cutter to be drawn into the temple-head, as inthe patent referred to, drawing the filling end across the blade at andsevering the end at that point usually before the heel E of the templeis engaged by the lay to move the temple and the cutter back for theirfull stroke.

Upon the heel B of the temple I attach a cushion,shown as a piece ofleather M, held in place by a rivet m, or in other suitable manner, thecushion passing across the front of the heel and extending laterally infront of the heel c of the cutter, but unattached thereto. This cushionis thus interposed between the two heels and the lay and breaks orrelieves the force of the blow. Whatever the adjustment of the templethe cushion is always in proper position. It is in plain 8o sight of theweaver and can be readily renewed when worn. It is small in extent andreadily secured in place.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. A reciprocating temple provided with a depending heel and a blade, acodperating cutter blade having a heel, said heels being adapted to beengaged and moved by the lay, 0 and a cushion attached to thetemple-heel and extended laterally in front of but unattached to theheel on the cutter-blade.

2. A reciprocating temple provided with a blade, a eoeperatingcutter-blade having a name to this specification in the presence of heeladapted to be engaged by the lay, and two subscribing witnesses. afiexib e cushion attached to the tem 1e and 1 extended in front of andindependen of the JAMES NO-RTHROP' 5 heel of the cutter-blade, to breakthe force of Witnesses:

the blow of the lay thereupon. HERBERT S. MANLEY, In testimony whereof Ihave signed my GEO. OTIS DRAPER.
